Starting new DIY amp with TPA3255

[RaahulT]

Hi Friends,
I have started on a path of building a DIY amp with TPA3255 board.
Board has been ordered.
Power through transformer 48v.
I have referred available information and posts by FMs on HFV and relevant post by FM @vizeta in particular.

Board: Ordered from Amazon Japan. Details were in Japanese. So posting this link in english.

I suppose a rectifier board would be needed for transformer. So I could find out this one.

VASP Electronics 10A 50V Max Power Supply Board for Audio Amplifiers & DIY Projects using 10A10 Diode & 2200uf capacitors https://www.amazon.in/dp/B07KSVCWBY...abc_KBRNYCYPBFEKEYND631E?_encoding=UTF8&psc=1

Should I go for any specific brand of transformer and rectifier board?

smps supply would have been better
Meanwell or something good. Anyways best wishes for the build. TPA3255 is great sounding amp.

Hi. Thanks for the encouragement.
Mean well 48vx7.35A is in transit. Expected shortly. I have received 40V transformer. Will be checking the difference, if any which I can hear, with smps and using transformer too, just out of curiosity.

Update:
1. Amp board, cabinet, smps 12v, 5v, transformer 40-0-40, misc items received.
2. Meanwell Smps 48v & generic 24v shipped

I also have a 7498 board which needs 24v/36v dc.
Since the cabinet is large enough, planning to put both (3255& 7498) inside with separate power supplies.

Sorry for late reply
Cabinet is heavy, pre-drilled holes, with fans and few fittings. Need to plan the inside layout accordingly, else I need to drill holes if required.

1. Meawell purchased from banglore based https://www.electronicscomp.com/lrs-350-48-mean-well-power-supply-350w-48v-7.3a?search=Mean well 48v

2. Amp board I ordered on Amazon.co.jp though it's available on Amazon.in too

3. Cabinet from amazon.in, as I could not locate better one or acrylic material nearby

Hope you could put up the things together and get it running.
